创建、更改和删除视图
在 SQL Server 管理对象 (SMO) 中,SQL Server 视图由 View 对象表示。
示例
若要使用所提供的任何代码示例,您必须选择创建应用程序所需的编程环境、编程模板和编程语言。有关详细信息,请参阅如何在 Visual Studio .NET 中创建 Visual Basic SMO 项目或如何在 Visual Studio .NET 中创建 Visual C# SMO 项目。
在 Visual Basic 中创建、更改和删除视图
此代码示例显示如何使用内部联接创建两个表的视图。该视图是使用文本模式创建的,因此必须设置 TextHeader 属性。
'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks2008R2 database.
Dim db As Database
db = srv.Databases("AdventureWorks2008R2")
'Define a View object variable by supplying the parent database, view name and schema in the constructor.
Dim myview As View
myview = New View(db, "Test_View", "Sales")
'Set the TextHeader and TextBody property to define the view.
myview.TextHeader = "CREATE VIEW [Sales].[Test_View] AS"
myview.TextBody = "SELECT h.SalesOrderID, d.OrderQty FROM Sales.SalesOrderHeader AS h INNER JOIN Sales.SalesOrderDetail AS d ON h.SalesOrderID = d.SalesOrderID"
'Create the view on the instance of SQL Server.
myview.Create()
'Remove the view.
myview.Drop()
在 Visual C# 中创建、更改和删除视图
此代码示例显示如何使用内部联接创建两个表的视图。该视图是使用文本模式创建的,因此必须设置 TextHeader 属性。
{
//Connect to the local, default instance of SQL Server.
Server srv;
srv = new Server();
//Reference the AdventureWorks2008R2 database.
Database db;
db = srv.Databases["AdventureWorks2008R2"];
//Define a View object variable by supplying the parent database, view name and schema in the constructor.
View myview;
myview = new View(db, "Test_View", "Sales");
//Set the TextHeader and TextBody property to define the view.
myview.TextHeader = "CREATE VIEW [Sales].[Test_View] AS";
myview.TextBody = "SELECT h.SalesOrderID, d.OrderQty FROM Sales.SalesOrderHeader AS h INNER JOIN Sales.SalesOrderDetail AS d ON h.SalesOrderID = d.SalesOrderID";
//Create the view on the instance of SQL Server.
myview.Create();
//Remove the view.
myview.Drop();
}
在 PowerShell 中创建、更改和删除视图
此代码示例显示如何使用内部联接创建两个表的视图。该视图是使用文本模式创建的,因此必须设置 TextHeader 属性。
# Set the path context to the local, default instance of SQL Server and get a reference to AdventureWorks2008R2
CD \sql\localhost\default\databases
$db = get-item Adventureworks2008R2
# Define a View object variable by supplying the parent database, view name and schema in the constructor.
$myview = New-Object -TypeName Microsoft.SqlServer.Management.SMO.View `
-argumentlist $db, "Test_View", "Sales"
# Set the TextHeader and TextBody property to define the view.
$myview.TextHeader = "CREATE VIEW [Sales].[Test_View] AS"
$myview.TextBody ="SELECT h.SalesOrderID, d.OrderQty FROM Sales.SalesOrderHeader AS h INNER JOIN Sales.SalesOrderDetail AS d ON h.SalesOrderID = d.SalesOrderID"
# Create the view on the instance of SQL Server.
$myview.Create()
# Remove the view.
$myview.Drop();
